GERMOND CENTRIFUGAL GOLD AND MINERAL SEPARATOR Filed Sept. 11, 1930 2 Sheets-Sheet 2 Patented Apr. 19, 1932 srrss Para earce OATMER GERMOND, F BEND} WASHINGTON 'CENTRIFUGAL GOLD ANDMIENEBIADSEIABA'EOE Application filed September 11,.-1930. Serial No. 481 ,2831- This invention relates to a machine designed for recovering gold and other precious minerals from ocean or beach sand.

The primary object of the invention isthe provision of a machine of this character em-,

bodying a stationary worm or spiral, and a tubular casing in whlch the worm or splral is positioned, means being provided for rotating the tubular casing around the worm' or spiral to cause the material to feed through the machine and accomplish the purpose of the invention.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combi- Figure 1 is a side elevational view of a' machine constructed in accordance with the invention.

Figure 2 is a front elevational view of the machine.

Figure 3 is a longitudinal sectional view through the machine.

Figure 4 is a plan view of the machine.

Figure 5 is a sectional view taken on line 55 of Figure 3. Y 7

Figure 6 is a sectional view taken on line 6-6 of Figure 3.

Referring to the drawings in detail, the device comprises a body portion 5 that has a tapered lower end portion 6 that terminates in a straight section 7 in which the valve 8 is positioned, which valve controls the passage of material through the body portion 5.

Secured within the body portion 5 and arranged adjacent to the upper end thereof, is a caring member 9 in which the upper end of the tubular casing 10 is mounted, the tubular casing 10 being shown as formed with an enlarged upper end portion 11 to support the tubular casing.

A hearing member indicated at 12 is also secured within the body portion at a point. in spaced relation. with: the bearing: member 9,

' the latter bearingmember also acting as a support for the tubular casing 10 Openings 13 areformed inthebod'y porc tion 5" and are disposed at'. points substantial l'y' intermediate the" ends of the body portion 5, the openings being provided to allow material to pass from the body portion 5.

Secured to the upper end of the body portion 5, is a frame 14: to which the funnel 15 is connected, the funnel being provided with a lower flange 16 cooperating with the flange- 17 of the tubular casing 10 to prevent material from passing between the upper end of the tubular casing and member 15. The lowor end of the tubular casing 10 is closed by means of the cap 18, to prevent the passage of material directly through the tubular casing. Openings 19 are formed in the tubular casing and are spaced from the cap 18, to permit material to pass laterally from the tubular casing. Disposed within the tubular casing 10 is a stationary worm or spiral 2O which is formed with a shaft 21 that extends means of the bolt 23.

An opening 24 is formed in the body portion 5 to accommodate a power gear not shown, which gear is designed to mesh with the pinion 25 that is keyed to the tubular casing 10, to the end that rotary movement may be imparted to the tubular casing, by any suitable power device. I

From the foregoing it will be obvious that due to the construction shown and described, material may be fed into the funnel 15, from where it gravitates into the tubular casing 10, which is rotated.

As the tubular casing rotates around the stationary worm 20, the material will be agitated and forced laterally through the openings 19, from where it passes into the body. portion 5.

The material passes into the body portion and collects in the body portion until it reaches the openings '13, from where the material passes outwardly to a place of deposit.

It is obvious that the heavy particles of gold or metal will fall to the bottom of the body portion, from where the same may be removed through the valve 8.

O I claim:

A machine for recovering precious metals from sand, comprising an elongated body portion having a tapered lower end provid ing a restricted lower portion, a rotary tubu- 10 lar casing within the body portion, the lower end of the casing extending into a restricted end of the body portion, a cap rem'ovably mounted on the lower end of the casing, and normally closing the lower end of the casing,

said casing having openings above the cap to allow material to pass laterally from the casing, a spiral mounted within the casing, and means for rotating the casing around the spiral to force material to the lower end of 579 the casing.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.

OATMER GERMOND.
